Invertible matrix
... matrix may have a left inverse or right inverse. If A is m-by-n and the rank of A is equal to n, then A has a left inverse: an n-by-m matrix B such that BA = I. If A has rank m, then it has a right inverse: an n-by-m matrix B such that AB = I. A square matrix that is not invertible is called singula ...

Chapter 18. Introduction to Four Dimensions Linear algebra in four
... This formula is called Cramer’s formula and it applies to square matrices of any size. It generalizes the formula we used for inverses of 2 × 2 and 3 × 3 matrices. Cramer’s rule shows that A−1 exists if and only if det(A) 6= 0. Earlier, we have seen this is equivalent to ker A = {0}. Thus, the foll ...
